. Application filed May 22, 1901.

To all whom, it may concern;

Be it known that I, ISAAC KLING, of Louisville, in the county of Jefferson and State of- Kentucky, have invented certain y new and useful Improvements in Compound or Multicylinder Engines; and I hereby declarethat the following is a fnll,clear, and exact description thereof, reference bein ghad to the accompanyiug drawings, which form Y specification.y

This invention is an improved compound or multicyhnder engine; and its objectis to produce a non-dead-centering engine, one wherein the pa'rtsarel assembled in compact space, wherein the cylinders exert their power through direct gearing upon a common shaft plete engine. Fig. 31is alongitudinal sec` tion therethrough; Fig.'4,1a transversevertical section; Fig. 5, an enlarged verticall sec-1 tion through one of theValve-chambers and connected parts.

Referringto the drawings, vAdesignates thev mainshaft, supported inbearings in standard B, attached tothe *base C. Upon this shaft is loosely mounted a IargeHy-Wheel 'or drum D, to the'inner face of which is secured a gear` d, and on this shaft are also mounted two plates E E, in-which are journaled equidistant crank-shafts F F,(three being showm) which lie parallelwith shaft A, and on their inner ends have pinions f, meshing with the gear d, as shown. Between `the plates E E are cylinders G, which are supported' on the plates E, so as to oscillate therebetween by trunnions g g1', which are preferably'placed near the inner end of the cylinder to lessen' the oscillation of that end thereof. The trunnion g is larger than trunnion g', and through part of this serial No. 61.4.53. (No modem it opens the exterior ends of the cylinderports H h, which respectively lead to opposite ends of the cylinder, as shown. (See Fig. 5.)

The cylinder-pistonsGrl are directly connected by rods G-to cranks F on shafts F, respectively, as shown. g rIvhe ported trunnions g project through 'openings e in the outermost plate E and are inclosed by a valve-.chamber I, (one for each trunnion g,) `toy which steam is admitted through an inlet-port 2'., communicating by suitable pipes 1213 ILl with a main steam-'pipe I5, connectedto a suitable steam-boiler. The admission of steam from -pipe I5 maybe controlled by a suitable governor, (not shown,) actuated from one of the rotating parts, preferably from one of the'shafts 'Ff Within each valve-chamber I and fitted closely against thedressed outer face of the trunnion gthereinis a valve J, which is of peculiar :construction The-valve has two chamber'sjj, thelatter being-closed on all sides and extending from theinner face of the valve through the stein or trunnion ofthe valve, as shown, communicating at the-outer .end of the trunnion through la'teral perforationsj2 with a chamber I' in theen'dof the' haust steam from opposite endssof the cylin.`

IOO

the cylinder controlled by the valve. This rod lean be adjusted so as to regulate the extent and throw of the valve, and thus the time and extent of admission of steam to the cylinder. The valve oscillates oppositely to the trunnion, thus obtaining a quick and easy shifting of the ports. The employment-of an oscillating valve working in connection with and oppositely to the oscillating ported tru nnion of an oscillating-cylinder engine I consider very valuable in practice.

Further, I can operate myengine on the expansion principle by connecting the exhaust ot' the upper steam-chest to the inlet of the next steam-chest, and the exhaust of the latter to the inlet ot the third, and so on, as is obvious. Then this is done, the cylinders should be of successively greater diameter, as required in all compound expansion-engines.

Operation: As shown, shaft A is fixed and plates E are fixed thereon, while drum D and gear d are free to revolve. Consequently when steam is admitted to the cylinders they rotate shafts F, and the latter through pinionsf rotate gear d and drum D. From the latter power may be transmitted by belts or in other desired manner. The relative power and speed imparted to drum D depends upon the relative sizes of gears f and CZ and of coursealso upon the size ofi the cylinders and the number employed. It is not essential that shaft A be stationary, as the action would be the same ifplates E were loose on shaft and drum D keyed thereon. In the latter case power could be transmitted from either end of shaft A.

Preferably the plates and cylinders may be covered with a housing (not shown) to prevent accidental interference with the action oi the cylinders.

lVhile I have illustrated three cylinders in the drawings, a greater or less number may be used, according to power and size of engine wanted.

The engine may be caused to run either forward or backward by providing an ordinary reversing-lever and link connections with valves, so that the latter can be shitted before starting the engine, so as to admit steam to the desired ends of cylinders. I do not consider it necessary to illustrate such feature herein, as it is not claimed and can be readily applied by an engineer.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

1. The combination of an oscillating cylinder having a ported trunnion, with an oscillating steam-valve controlling the ports in said trunnion and means for oscillating said valve simultaneously with but oppositely to the cylinder.

2. The combination with an oscillating cylinder having its inlet and outlet ports leading through one of its trunnions; with an oscillating main valve tted against the trunnion and controlling the ports therein and means l'or oscillating said valve simultaneously with but oppositely to the cylinder, substantially as described.
